Stuart Holden works out with team

Midfielder Stuart Holden is back with the U.S. national team for the first time since injuring his knee last summer, U.S. Soccer confirmed on Tuesday.

Holden, who tore his right ACL while playing for the U.S. against Panama in July’s Gold Cup final, joined the American squad as a guest Tuesday in Carson, Calif., where an MLS-heavy roster is preparing for Saturday’s friendly against South Korea (5:30 pm ET, ESPN2/WatchESPN).

Holden will not be available to play in the match, but has been medically cleared to participate in some of the team’s training drills this week, a team spokesman told ESPNFC.com on Tuesday afternoon.

Holden represented the U.S. at the last World Cup in South Africa in 2010. He is hoping to return to full fitness in time to make the final 23-roster for this summer’s tournament in Brazil, although time is short and competition for spots is at an all-time high—especially in the crowded U.S. midfield.

The 28-year-old Holden debuted for the Yanks in 2009 but has been limited to just 25 caps due to a variety of serious injuries. The Bolton star broke his leg in March 2010 friendly against the Netherlands, limiting to just four minutes of action off the bench in South Africa.

He injured his left knee in English Premier League game against Manchester United the following year, and didn’t play for the U.S. at all in 2011 or '12.

Holden made eight appearances for the U.S in 2013. He has yet to for Bolton this season.
